RALPH NULL AND CHRISTOPHER C. SHEPI-IARD, OF CHADRON, NEBRASKA.

PUNCTURE-CLOSING SOLUTION.

No Drawing.

To all whom it may concern:

Be it known that we, RALPH N011. and CHRISTOPHER C. SHEPHARD, citizens of the United States, residing at Chadron, in the county of Dawes and State of Nebraska, have invented certain useful Improvements in Puncture-Closing Solutions, of which the following is a specification.

The object of our invention is to provide a fluid compound to be poured into an inflatable tire such as used on automobiles, etc., for closing punctures or blow-outs in the same, and which shall contain no ingredients harmful to the rubber of the tire, and which shall be the simplest possible composition which will possess all the necessary properties of such a compound.

Other objects will be explained in the following description, and the invention will be more particularly pointed out in the claim appended hereto.

In forming our improved composition we take equal parts by volume of distilled water and alcohol, and to each gallon of this liquid add three ounces (adv.) of a filler such as paper pulp and silk fiber, although for the latter we may substitute other forms of wood fiber, or straw or cotton fiber.

Specification of Letters Patent.

Patented Apr. 29, 11919.

The composition is placed in the tire, where it will remain in a liquid state, in sufficient quantity to cover the interior surface of the inner tube. When in use, the revolving of the wheel will keep the composition spread to the parts of the tire liable to punctures, and if a puncture occurs, the composition will close the same, as it will not remain in a liquid state when exposed to the atmosphere.

What we claim, is:

A compound of the class described, consisting of equal parts by volume of distilled water and alcohol, there being admixed to each gallon of said liquid three ounces (adv.) of a filler such as paper pulp, and silk fiber, the liquid serving to carry the fiber and pulp to a hole in a tire containing the compound whereby a mat is formed inside the tire so as to bridge said hole, the silk of the mat forming the stringers of said bridge and the pulp the plank of the bridge.

In testimony whereof we aflix our signatures.
